bioprene, I like it!

while I do not dive an rEvo, I thought I would weight in...

I use off board gas for all bouyancy control; wing as primary BC only enough gas in the DS to keep off the squeeze.

the off board I use is a butt mounted bottle which will also be my bailout for shallower dives when no "stage bottles" are needed.

I look at all on-board gas as being dedicated to life support only! I have OC bailout to on-brd DIL, that's it.

At the risk of starting the Ar discussion; I like keeping the bouyancy gas breathable... that way all gas I am carrying can be used in a pinch, if absolutely necessary...

my 2 cents.
